DEVICE FOR PROPELLING VESSELS` SPECIFICATION forming part of Lettere Patent No. 569,951, dated October 20, 1896.

Application filed December 17, 1895. Serial No. 572,407. (No model.)

To ctZl whom it may concern:

Be it known that I, JOHN BOND, a citizen of the United States, residing at Tu rlock, county of Stanislaus, State of California, have invented an Improvement in Devices for Propelling Vessels; and I hereby declare thel following to be a full, clear, and exact description of the same.

My invention relates to improvements in the propulsion of vessels; and it consists of the parts and the constructions and combinations of parts hereinafter described and claimed.

My present invention is an improvement upon the device for which a patent was issued to me November 19, 1895, No. 550,037.

Referring to the accompanying drawings, Figure 1 is a general view of my propelling device. Fig. 2 is a section on line y Iy, Fig. 3, in the direction of the arrow. Fig. 3 is a section on line of Fig. 2.

The vessel A may be constructed in any suitable or well-known manner, having the floor properly formed to produce the least resistance when moving through the water. Beneath the fioor of the vessel are the cylinders B, one at each end of a central eompartment B', which latter is formed by a depression in the floor of the vessel. This central depressed portion serves to contain the engine-cylinders F F, which are essentially in line with the plunger-rods E, with which the engine-pistons are connected in any suitable or desired manner. The ends D of the central chamber B' are provided with stuflingboxes, as shown at D/, through which the plunger-rods E pass and by which a tight joint is formed.

The cylinders B are opened at the outer ends` At their inner ends they are surrounded by a cylinder 132 of larger diameter, which forms a part of B, and this cylinder has a flange BS, by Which it is bolted to the head D, thus making these cylinders practically a part of the central chamber B', but at the same time removable whenever it is necessary for any purpose. The annular head formed by the connection of the smaller cylinder B with the larger one 132 has perforations or openings made in it, as shown at a, and these openings connect inside of the part B2 with the interior of the cylinder B by slots or channels, as shown at b. The object of this construction is to allow the piston to draw water in through these openings when making an outwa-rd stroke and to force it out when making an inward stroke.

The Operation will then be as follows: The engine being setin 1notion,the plunger moving inwardly will draw water-in through the open outer end of the cylinder, and when the plun- .ger moves outwardly it forces the Water out again through this outer end, and when the high piston-speed is maintained the momentuln of this jet of water thus forced outwardly will act against the body of water in line with' the cylinder and serve to propel the vessel in the opposite direction. As the piston O moves outwardly it produces a Vacuum in the interior end of the cylinder, and water will thus be drawn in through the passages a, and the rear portion of the cylinder will thus be filled with water. When the pistonl returns in its stroke, it again forces this body of water out through the openings cc and in the same direction with the openingin the outer end of the cylinder, thus again creating an impact of the jets of water against the body of waterin which the vessel is immersed. By this Operation it will be seen that both strokes of the piston serve to force the body of water outwardly and the apparatus becomes double-acting.

Thenever for any purpose it is desirable to close the openings to the cylinder, I einploy gates for the purpose. The outer gate G is in the form of a disk or cone,-of sufficient diameter to cover the exterior Opening of the cylin der, suitably braced and having a leverarm I-I fulcrumed at I and extending to a point within the vessel or a chamber therein, by which arm it may be actuated.

The inner end of the lever-arm l-I is connected with a Screw or other actuating mechanism, as shown at J, by which it may be moved in an are of a circle, so asto close against the outer end of the cylinder B. VVhen it is opened, the disk G is swung up against the bottom of the vessel and entirely out of line of the cylinder.

In order to close the openings cc in the cylinder 132, I have shown an annular ring` K, having holes made in it which are coincident with the holes a when the apparatus is in lOO condition to operate, but which7 by a slight movem ent of the disk K, maybe moved out of line with the opening's, .so that the unperforated portion of the ring1 will cover the holes cc and thus close the Opening` into the cylinder. This device may be operated in any suitable manner. A convenient way is here shown by forming a portion of the interior or exterior circnmference of the ring' K with teeth k, which are eng'ag'ed by corresponding` teeth on a pinion L. This pinion is fixed to a shaft M, which extends through the head I) to a point in the central chamber B' and by means of a hand-Wheel or other connection fixed to the interior end the ring may be turned to either open or close the passagcs a, the object being` to temporarily prevent the water from entering` the piston-chamber.

I-Iavingl thus described my invention, what I claim as new, and desire to secnre by Letters Patent, is-

1. In a vcssel, open-ended cylinders located below the bottom of the vessel essentially in line with each other, an intermediate enginecompartment, connections between the engines and plungers which are adapted to reciprocate in the outer cylinders, cylnders of larger diameter intermediate between the outer ends of the plnng'er-cylinders and the central compartment having` annnlar heads Connecting them with the smaller plungercylinders, perforations cxtendling longitudinally in annular series within said heads, with transverse slots or channels Connecting the perforations with the interior of the enlarged cylinders whereby the water is admitted to the interior end of the plunger-cyll inders and expelled therefrom by each reciprocation of the plunger and water is admitted to the outer end of the plunger-cylinders and expelled therefrom by the opposite movements of the piston and gates whereby the end of the oylinder and the anuular opcnings of the larger cylinder may be closed or opened.

2. In a vessel open-ended cylinders located below the bottom of the vessel, essentially in line with each other, other cylinders of larger diameter Connecting With the inner ends of the first-named cylinders, With heads at their jnnction7 provided with an ann ular series of passages with slots or channels leading` from said passages to the interir of the enlarged cylinders, plungers re'cprocatingl within the smaller cylinders, a central engine-compartment and mechanism by which the plungers are reciprocated, a perforated rotatable ring,I at the outer ends of the passages, and mechanism by which said ring,` is turned so that its perforations coincidc with those of the annular cylinder-head, or close them, as deseribed. 4

In a vessel, a central engine-chamber located beneath the bottom of the vessel, open-ended cylinders of different diameters extending` in line with said chamber, plungers reciprocating in the outer and smaller cylinders and connected with the engnes of the central chamber, annular perforatcd ring-s, and mechanism by which they are rotated over the openings in the heads-of the larger cylinders, and swing'ii'lg gates and operating' mechanism connected with a leverarm thereon by which the outer ends of the smaller cylinders are elosable.

In Witness whereof I have herennto set my hand.
